EXCAVATING, STRIPPING, AND CONVEYING MECHANISM.

.new and useful Improvements in Excavating, Stripping, and ConveyingMechanisms; and I do hereby declare that the following is .a full,clear7 and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

It is frequently desirable to strip from considerable areas, the earthoverlying beds of coal, stone or other valuable material which it isdesiredI to remove. Such work is very expensive owing to the necessityof transferrin the material from the surface for a considerable distanceto expose the under stratum to mining operation. The ordinary'excavatingmechanisms do not operate to advantage for the reason that constantshifting interferes with rapid work. Furthermore in such o eration it isusual to transfer or deliver t e surface material to the area from whichthe lower minera deposit has been removed. For such an o erationordinary steam shovels do not well suilice and owing to the peculiarconditions under which the work is carried forward and lthe necessity ofeither working longitudinally with the deposit or transversely the mainline thereof, it is necessary to transfer further than is possible witha power shovel.

The object of this invention is to provide cooperating stripping andconveying mechanisms whereby the superposedmaterial may be removed bymeans o f suitable power shovels and delivered therefrom to a selfpropelling oonveyer,. movable alone' the saine track or upon a aralleltrack closely adjacent thereto, and w ereby the excavated materialstripped from the vein or ldeposit is delivered laterally to any desireddistance.-

4It is a further object of the invention-to provide in connection with apower shovel adapted to rotate from its filling position to dumpingposition to deposit its load, a suitable conveyer operating transverselythe working and movable along a track independently of the shovel toreceive the cona tents of the dipper.

It is thus an object of the invention to Specification of LettersPatent.

Fig. 11 is a similar view showing the shovel o)erating straight ahead. Fig. 1; illustrates tlie conjoint use of ashovel such as shown in Figs. 6 and 7 and a conveyer movable along atrack parallel therewith. Fig. 13 is a view in plan and horizontalseetion of the transmission gear. Figs. 14 and 15 are details of a partof the adjusting mechanism for the frictions.

Asshown in said drawings; A power shovel is employed to uncover a veinof coal A, removing the superposed rocks and niaterial A therefrom anddelivering it to a conveyer from which it is delivered to a dump A2beyond the uncovered stratum. For this purpose any suitable power shovelmay be used as for instance such as indicated as -a whole b.y B or B.The shovel B is a faniiliar type the same is mounted upon a platform bsup orted on trucks b as is usual and upon whicii is mounted the steamboiler b2 and hoisting engines C so disposed upon the .the side sillsthereof.

platform as to serve as a counterweight for the dipper D operated fromthe boom D.

The engine as shown, though'not necessarily, is a double hoisting enginethe cylinders c-c of which are arranged horizontally and drive to a drumshaft C on which4 between the connecting rods is provided a pinion c2,which drives a gear c3, secured'on the hoisting drum C2, which isjournaled in advance of the main shaft C.v

At the forward end of'the car is secured a circular platform or pedestalE, on which is removably mounted the boom platform E, on which issecured-the lower end of the in' clined boom D The upper end of saidboom is supported at the desired inclination by means of stay rods ewhich extends from the head of the boom rearwardly and downwardly' andpivotally engage or swivel 'on the u per end of the mast E2, the lowerend of w ich is secured on the carat the rear of said boom platform andwhich inclines forwardly to a point above the center of said platform.Stay rods e/ extend downwardly from said Vmast one on each side of thecar and are rigidly engaged at their rear ends to Mounted upon said boomis a thrusting engine F, on the shaft of which is rovided a pinion shownin dotted lines in gig; 6 and on which meshes the racked under side vofthe dipper stick d. A suitable cable dis secured at one end to the.upper end of the boom and leads through a sheave d2 in the bail of thebucket D, over a saddle sheave d3, atl the'v end of the boom and oversheaves d4 and d5 on said boom, and thence downwardly through the centerof the boom platform to a sheave d6 and thence to the hoisting drum C2.Suitable operating le- -vers G are rovided and as shown an engine G isprovi ed connected with suitable ears, to drive a shaft g journaledbelow the sil s and from which suitable sprocket chains or otherconnections g2 drive to the axles of one or both trucks thus making theshovel automobile andpermitting the same to move in either direction.Drums c4 and c5 are provided on the ends of the mainshaft C and suitablelines lead to th'ese to revolve the platform in swinging the dipper.

The construction shown in Figs. 4, 5, 8 and 9 indicates a power shovelin which. the -entire platform rotates upon 'the truck. For this purposea single truck b5 is used and pivotally supported thereon is theplatform for the shovel which'is journal'ed at the center of the truck.-A boiler b2 is supported upon the rear end of the platform an with theengine C affords a counterweight for the boom and the dipper. The pinionc2, secured on the engine shaft, intermeshes with a gear c3on the drumshaft c and drives the hoisting drum C. The boom D3 is supported uponthe front end of the platform at a suitable inclination and is providedwith a saddle 'with both the bevel gears c8-c".

sheave d? at the upper end thereof on which the bucket D` is suspendedas before described With-reference to Fig. 6. The dipper stick d is alsoprovided with a rack on the under side thereof and extends rearwardlybetween the legs of the boom and engages a suitable pinion shown indotted lines in Fig. 4 and which is driven by suitable train of gearsindicated as a whole by d8, from an engine F supported on the boom. Stayrods e3 extend from the upper end of the boom rearwardly and engage onthe rear end o-f the platform 'as shown in Fig. 4, and are each providedwith a turnbuckle e2 whereby they ma be adjusted.

In advance of the drum sha t and parallel therewith a shaft C4 isjournaled on which is secured a ear c7, which meshes with the gear c3. Aso secured on said shaft are inwardly facing bevel gears c-c" betweenwhich is' provided a clutch c1 of any suitable kindada ted to engageeither to the shaft.

Journale in the platform of the car is a vertical shaft C5 on the upperendof which is provided abeveled pinion c, which meshes y At the lowerend of said shaft is provided a pinion c12 which meshes with a lar egear b rigidly secured to and concentric with said platform and whichrotates the same When driven by the pinion cl2. Any suitable arrangementof o erating leversand throttles may be emp oyed and any suitable drivemay be arranged tov propel the trucks upon the track either by the sam'eor separate engines.

The conveyer com rises an automobile platform car H, provided at itsrear end with a steam boiler h thereon and having mounted convenientlyupon the lcar a hoisting engine I, such as ybefore described andconnected with the steam boiler in any suitable manner. A pinion Q', issecured on the driving shaft which meshes with a gear y' on a winchshaft J, journaled transversely the car in advance of the middlethereof. Rigidly secured upon a sleeve y" through which said winch shaftJ passes is a beveled gear y'2. On the outer end of said sleeve isprovided a friction pulley js adapted to be enga ed by complementalfriction pulley jf feat ered on said shaft, and which when saidfrictions are brought into en a ement drive said bevel gear. Journa elongitudinally of the platform is a shaft K on the end of which in meshwith the gear j is a bevel pinion k.

Secured upon the forward end of the car and extendingtransversely-thereof is va conveyer indicated as a whole'b -L, and whichcomprises parallel ways or sillhl ofany suitable length which extendlaterall from the carat any desired inclination an on which arejournaled transverse rollers Z the ends of which are greater in diameterthan the portion intermediate the ends. Trained over the said rollerslongitudinall of the ways and around suitable rollers of arger diameterZ2 at the outer end of the ways and corre- I o is held from rotation ineither case by the spending roller Z3, at the inner end thereof near'the o posite side of the car is a conveyer belt A frame L is providedon said 'er d of the car and extending above the inner end of saidconveyer and rods or cables Z-Z are secured at the outer end andintermediate the ends of the conve er and secured on said frame tosupport sai( outer end. As shown also at the side of the car oppositethe conveyer and supported at its outer end on said frame by means ofrods or cables Z7 is a counterweight platform L2 which may be of anydesired size and upon which may be loaded rock or any desired materialto serve as a balance for the Weight of the conveyer and its load.

Above the inner end of the conveyer upon the car is a hopper comprisingside members ZS rigidly secured to said frame and to the Ways of theconveyer, and which serve to direct all material delivered thereto uponthe middle of the belt. As shown the roller or pulley l2 at the outerend of the conveyer is driven by means of a grooved shcave l on the endof its shaft about which and a corresponding sheave k2 on the end of theshaft K, is trained a cable to afford a rope drive though obviouslysprocket wheels and a sprocket chain may be used for this purpose ifdesired. l

It is sometimes desired to break up the material or pulverize it beforedelivery to the -conveyer.

y positely by means of a shaft m journaled parallel therewith and drivenby means of suitable sprocket wheel thereon and on said winch shaft J bymeans of sprocket chain m2.

0n the outer end of said shaft m is a gear m?,

whiclrmeshes with one of the corresponding .intermeshing gears m4 on theends of the beater shafts M and M.

Any suitable shifting mechanism may be employed. As shown in Figs. 8, 14and 15 however, a thrust rod O extends axially into the shaft J andengages a block o which extends transversely lthrough the shaft andbears against the outer side of the friction y, said rod O extends intoa casing o and is provided witha circular head 02 thereon against whichpresses a circular head o3 having balls therebetween to reduce friction.The head O of the casing o su ports a bearing o4 for a threaded shaft o5wiiich is threaded therethrough and extends through the head into abearing in the head o3 and by inward rotation forces the friction j*against its complemental member js driving the gear In a similarmanner'the friction o" may beengaged on the complemental face of thegear y' of course compressed air may be used in said easing o if desiredinstead of the screw 0". rl`he head teeth oB which mesh with teeth o onthe head O. Means are also provided for propelling said car by theengine whereby the conveyer is operated. For. this purpose a sprocketwheel is provided on the driving shaft of the engine and on a shaft N ofa transmission mechanism and about the same is trained a sprocket chain'n so that said shaft N is d riven continuously when the engine is inoperation. Journaled in the transmission 'frame' n are shafts N and N 2parallel with the shaft N, and provided each with intermeshing gearsn2-n3 of which the gear n2 is in mesh with a pinion a4 on the shaft N sothat said gears rotate continuouslyon their shafts. Rotatable on saidgear shafts N and N2 are concave frictions nL-n each provided with apinion a7 and as rigidly engaged thereto and which mesh with a gear nrigidly secured on a shaft N3 journaled below the platform. Each of saidfrictions 11S-nf' are arranged to engage respectively complementalconvex 'faces n on the adjacent side of the gear on the same shaft, andany suitable mechanism may be, employed to shift either the concavefriction or the gear longitudinall of the shaft into frictionalengagement, tiereby driving the shaft N3 either forwardly or in reversedcpendent upon which of said frictions is engaged. As shown sprocketwheels are vided on the inner end of the shaft N 3, w lich drive tocorresponding sprocket wheels on the axles of the rear truck by means ofsprocket chains n.

In the constructions in which the beaters are not required thetransmission before described may be omitted and in such case thesprocket wheel on the winch shaf t is utilized to drive a sprocket chainn2 which is trained around a corresponding sprocket wheel on one of thetruck axles as shown in Fig. 3.

The operation is as follows: Referring to Figs. 1, 10, 11 and 12 instripping, a track is laid upon the vein or stratum uncovered andashovel s uch as the type shown in Figs. 6 and 7 and 12 or shown inFigs. 4, 5, 10` and 11 is operated on said track to strip the superposedmaterial from the coal or other material and delivers the samejnto theconveyor indicated as a whole by X, which may be movable along the sametrack as shown in Figs. 10 and 11 or upon a parallel track as shown inFigs. 12, if the shovel B is used. As the excavated material isdelivered into the ho per the conveyer transports the same laterallgyfor any desired distance within its TVO- range and deposits it beyondthe edge of the may be varied without departing from the principles ofmy invention.
